We have bee having an issue with our 1995 felicia 1.3 spi (not mpi) engine 136B

 

New spark plugs, leads, serviced. No blown fuses. All grounds checked. 

I suspected to be the crank position sensor because the rpm gauge would jump randomly before car stalling. So I brought a Lucas one now the car wont start at all. I put the original one back in the car cranks for whole eventually start and dies few seconds after. Any ideas? thanks Adam

If changing parts caused a bigger issue you know you need to focus on ignition 

Where should I start looking? Thanks

The rev counter needle twitching used to be an indication of a fault with the ignition circuit, showing up low tension faults.  From ignition switch forward checking, relay,  wires and connections, perhaps wiggle tests, all wires and connections need to be clean, secure and protected.

 

Earths are a good thing to check but you might need to disconnect to check that they are clean, secure and protected.

 

Lucas is just a brand name now split over various companies and the products are not all the best, often not high quality. - "In 2003 the decision was made by TRW to license the Lucas brand to specialist licensees who could continue the development and investment of the Lucas programs."

Wrong part? Not compatible?

So now the car runs for about 20min and then just stops. After 10-15min rest it will start again. 

Any ideas?

 

thanks adam

So what has changed from 20 January when the engine started and died a few seconds later to now when the car runs for 20 minutes and stops then restarts after 10-15 minutes - you are a little sparing with the information you're giving out.

 

The stopping after 20 minutes and restarting after 10-15 minutes might be something to do with heat and environment, a fuelling thing possibly combined with with heat and environment, one, both, neither perhaps electrical.

 

What happens the engine stops, what happens if you try to start the engine before 10-15 minutes?

 

What are the makes of the new spark plugs and HT leads?

 

These type of problem are not uncommon and can have lots of causes, some very simple so often overlooked.

 

@Adamskii

You need to provide a lot more information about the history of the car before getting a meaningful answer.
